Question 1

UC has a requirement that an opportunity should have a field showing the value of its associated account's billing state. This value should not change after the opportunity has been created. Is there a recommended solution to configure this automated behavior?



Answer : C

Apex. This is correct because Apex is a programming language that can perform complex logic and manipulate data in Salesforce. Apex can be used to create a trigger on the opportunity object that copies the value of the billing state from the related account record when the opportunity is created, and prevents it from being changed afterwards. The other options are not suitable for this requirement because they either cannot copy data from a related object (formula field, roll-up summary field) or cannot prevent data from being changed (workflow).


Question 2

The developer at Universal Containers wants to test code in a sandbox environment. In order to ensure the code works properly, the sandbox needs to have at least half a gigabyte of dat

a. The sandbox will need to be refreshed after each three-day sprint.

What type of sandbox should the App Builder provision to the developer?



Answer : D

The app builder should provision a Partial Data sandbox to the developer. A Partial Data sandbox can have up to 5 GB of data, which meets the requirement of having at least half a gigabyte of data. A Partial Data sandbox can also be refreshed every 5 days, which meets the requirement of refreshing after each three-day sprint. Option A is incorrect because a Developer sandbox can only have up to 200 MB of data, which does not meet the requirement. Option B is incorrect because a Full Copy sandbox can only be refreshed every 29 days, which does not meet the requirement. Option C is incorrect because a Developer Pro sandbox can only have up to 1 GB of data, which may not be enough for the requirement.

Question 4

An app builder created multiple custom fields, page layouts, and reports in the sandbox and added them to a change set was deployed to production, the reports were NOT deployed.

What should the app builder do?



Answer : B

Moving the reports from the Unfiled Public Reports folder and adding them to a new change set is what the app builder should do to deploy the reports to production. According to theSalesforce documentation, ''Reports in the Unfiled Public Reports folder aren't available for deployment.'' Moving the reports to the Untried Public Reports folder, recreating the reports in production, and adding the reports to an unmanaged package are not necessary or recommended actions.


Question 5

What are two reason to create an unmanaged package? Choose 2 answers



Answer : A, C

The two reasons to create an unmanaged package are to distribute open-source projects on the AppExchange and to deploy from a Developer Edition environment. An unmanaged package is a collection of components that can be installed in any Salesforce org but cannot be upgraded or controlled by the developer. An unmanaged package can be used to share open-source projects or to deploy components from a Developer Edition environment to another org.


Question 6

Cloud Kicks wants to know the total value of all won Opportunities for Accounts and display it on the record.

What type of summary should the app builder use in the roll-up summary field?



Answer : C

The app builder should use Sum as the type of summary in the roll-up summary field. A Sum type of summary allows the app builder to calculate the total value of a numeric field from the child records related to a parent record by a master-detail relationship. The app builder can create a roll-up summary field on the Account object that sums the Amount field from the won Opportunities related to each Account. Count is not a valid type of summary, as it does not calculate the total value of a numeric field. A Count type of summary allows the app builder to count the number of child records related to a parent record by a master-detail relationship. Max is not a valid type of summary, as it does not calculate the total value of a numeric field. A Max type of summary allows the app builder to display the largest value of a numeric or date field from the child records related to a parent record by a master-detail relationship. Min is not a valid type of summary, as it does not calculate the total value of a numeric field. A Min type of summary allows the app builder to display the smallest value of a numeric or date field from the child records related to a parent record by a master-detail relationship.


Question 7

An app builder has deployed a change set from a sandbox to production. There is a long delay in the deployment.

What can be causing the delay?



Answer : B

The app builder should know that a field type change is included in the change set and that it can cause a delay in the deployment. A field type change is a change that modifies the data type of an existing field, such as changing a text field to a number field. A field type change can affect many aspects of Salesforce functionality, such as validation rules, formulas, workflows, reports, dashboards, and more. Therefore, deploying a change set that contains a field type change can take longer than usual and require more testing and verification. Option A, C, and D are not changes that can cause a delay in the deployment.
